To all whom it may concern:

Be it known that I, HUGO PAUL HAANEL, Jr., a citizen of the UnitedStates, residing at St. Louis, State of Missouri, have invented certainnew and useful Improvements in Pianoforte Attachments, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof.

My invention has relation to improvements in piano-forte attachments;and it consists in the novel features of construction more fully setforth in'the specification and pointed out in the claims.

The present invention is directed to that class of attachments which maybe exteriorly applied t the keyboard (if a piano for a purpose to behereinafter pointed out, and which may be readily detached when desiredwithout in any manner impairing the piano. The object of the inventionis to provide an instruction sheet or roll which shall wind onv rollersin proximity to the keyboard, and in so doing designate by suitablepointers or indicator strips, the notes to be struck by the performer. Afurther object is to give the performer (or student) instruction in therudiments of piano-forte by means of appropriate markings on the sheetor roll; a further object is to provide a piano-forte attachment wherebyone who is not a skilled pianist may be enabled to play piano com--positions without previous practice or in struction; a further object isto provide an attachment for the purposes specified that may be readilycontrolled by the operator, and one that is simple in its construction,and possesses other advantages more particularly pointed out in adetailed description of the invention in connection with theaccompanying; drawings in which Figure l is a perspective view of an upright piano-forte showing my invention applied thereto; 2 is a verticalcross-section through the roll on the line -r 2 of Fig. 1, parts of thepiano beiu, shown dotted; Fig. 3 is a vertical longitudinal section ofthe bracket-casing on the line 3 3 of Fig. 4; Fig. 4. is an outside cudelevation of the ln'acket-casing with parts broken away: Fig. 5 is aninside cud elevation oi the bracket-casing with parts broken away; Fig.(3 is a front elevation of the left-hand sup porting bracket with partsbroken away and with fragments of the rollers and sheet mounted thereon;Fig. 7 is a cross-sectional detail of the speed regulating cam taken onthe line 77 of Fig. 5; Fig. ,8 is a plan of one of the rollers with theinstruction sheet attached showing several of the pointers or indicatorstrips thereon; and Fig. 9 is a vertical cross-section through the upperroller on the line 99 of Fig. 3.

Referring to the drawings, P represents an upright piano-forte to thesidearms A, A, of which are clamped by means of screwclanips (l, C, thebracket 13, and bracketcasing ers R, R, mounted between them, the rol l,er B being in close proximity to the key ard K conu mscd of the keys in,la, etc. S represents an indicator roll of suitable material secured andnormally wound on the roller ll, and adapted to be unwound therefrom andwound onto the roller R upon passing the books it, h, at each end ofsaid roller through the perforated flaps e, c, imparting rotation to theroller R in a manner presently to be described. The roll S is providedthroughout its cator stri s or )ointers 2 unched from the body of thesheet M constituting the roll in such a manner that their free endswillbe re: rward with reference to the direction of travel of the roll as itwinds on the roller K (Fig. 2). The rollers R, R are provided at eachend with spindles g, 1, those of the roller R restiup in the bearing '1of the bracket it and bearing 1" of the casing li respectively.

The casing B is provided with a removable wall or cover '11, betweenwhich and the inner fixed wall to is mounted a main shaft 2, on which isrotatably mounted a. housing 3 provided with a lateral sleeve 4, saidsleeve ontomliugsubstantially the full length of the shaft 2. (oiled inthe housing 3 isa spring 5, the outer cud of which is secured in anysuitable manner to the peripheral wall of the housing, 3. while theinner end is sooured to the. shalt 2. lvlouutod on the shaft 2 andconfined between the wall w and outer B respectively, which have therollof the roll S, and

extent with indiend of the sleeve 4 is a ratchet 6 adapted to be engagedby a spring-controlled pawl T, and a Winding key ll is adapted to bescrewed onto the end 2' ol the shaft projecting from the easing B.

Mounted on and securely lixed to the sleeve *1 near the outer endthereof is a driving gear 8, meshing with a pinion U mounted on a shaft'10. The end of the shaft It) ad jacent the wall to terminates in aredttced portion 10 which portion has a bearing in said wall. Theopposite end of the shaft it) is provided with a socket 11/ forreceiving a stem .5 of an extension shalt ll. the stem be ing providedwith a pin said pin extending into and traversing slots II. n. onopposite sides of the socket 11/ of the shaft 10. Enveloping the stem sand confined between the shaft It) and extension ll is'a coiled spring12. which normally tends to 'lorce the extension ll out of the casing13. however. such movement being limited by the pin 1 striking the endsof the slots n. n. (Fig. I3). The extension shat't ll passes through thewall ur. in which it has a suitable bearing. and is provided at itsouter end with a polygonal portion 11 of reduced crosssection. Theprojection 13 is adapted to enter a socket 1/ ol corresponding shape inthe adjacent; end ol' the roller ll. and by l'oreing the extension 1,1slightly into the casing l3.

(which may he done by compressing the.

spring 12. the pin 1 traversing the slots n. 1/.) the spindle g on theopposite end of the roller t is permitted to enter the hearing 1'. I

The bracket B is provided with a lateral extension or arm la throughwhich the clamp screws. and the inner l'aces f. of the bracket are linedwith 'lelt 1.3 or equivalent material to avoid mart-ing the polishedsurl'aces ol' the piano with which they come in contact. The clamp (l isalso l'aced with'a similar material l5. (orrespomling laces f. f. ol thecasing F). and the clamp C, are lined sitnilarly to the bracket 1) andclamp 'lraversing the. wall u" of the casing B and mounted therein is asten lti provided at its outer end with a knob or head 17. and haviugacam 18 mounted on its inner end contiguous to the peripheral wall of thehousing I). Secured to the inner portion of the stem It is a spring iwhose tree end is provided with a teat or button it) of suitable'l'ormation adapted to enter one of a series ol depressions 'il on theinside l'ace ot' the wall 1/". upon turning the knob 14'. By reason ofthe eccentricity ol' the cam 1h it may' be brought to bear against thehousing It by tprning the knob to the right or it may be moved clear ofthe housing by turning the knob to the lett (Fig. 5). The cam 18 iscovered with felt. leather. or other yielding naterial so any degree ofpressure may be one of the keys Z: of the piano when it reaches acertain point in the rotation of the roll (dotted position. Fig. 2).said strip continuing to rest on the key during an interval depending onthe length of the strip. Whichever keys are touched. and thus indicatedto the operator. by the strips p. the operator will strike. and he willkeep the key depressed as long as the strip bears ou it. The strips maybe of different lengths-'- such as p, p, on the right hand side of theroll (Fig. 5). the long fingers imlicating a longer note than the shortones. i. 0., the lingers may designate half-notes and p eighth-notes.'hen the attachment is used as an instructor theindicator strips may bemarked by their proper letters corresponding to the note indicated. suchas t. E. ti. left hand, and Bb, E, right hand (Fig. s); the lingers tobe used may also be marked on the strips such as 5.3.1. left hand. and1.5, right hand. (Fig. 5). It is obvious that an unlimited amount ofinstruction notes and pointers may be placed on the roll h to assist thestudent. or guide an unskilled performer.

Rotation is imparted to the roll ll by the shaft 10 and extension 11.the pinion t) on the shaft It) being driven by the gear 8 mountedtightly on the sleeve 4 of the casing 3. The casing 3 is caused torotate by the spring 5, which is lixed to the casing and shaft 2 aspreviously described. and tightly wound tip by tttrning the key ll inthe direction indicated by the arrow (Fig. l). said spring beingprevented from unwinding by means ot the ratchet (i and pawl T as wellunderstood in the art. llowtwer. the spring is free to unwind in thedirection indicated by the arrow (Fig. 5) since the casing to which theouter end ol the spring is secured is loosely mounted on the shatt 2.-in unwinding the spring rotates the casing 5 at any desired speed.depending upon the pressttre that is brought to bear on the periphery ofthe casing 3 by the cam lo. controlled by the operator by tttrning theknob 1T. When the operator wishes to wind the spring he merely locks thecasing by turning the knob 17 to the right. .\t'ter the roll has beencon1- pletely unwound from the roller R and wound onto the roller t therollers are reversed. the polygonal portion 13 ot' the ex tension 11 isinserted into a socket o (similar to socket o in the end of roller i) inthe end of roller It. the casing 3 is released d the roll rewinds ontothe roller 1t. he roll eiiccting an unwinding of can now be removed anda new roll mounted in position over the keyboard oi the piano.

he roll S mustot course be as wide as the keyboard of the no so that itmay contain indicator str for any or all, the keys regardless theirlocation. on the keyboard.
